“…Regression coefficients are presented in Table 2. As indicated in Table 2, multicollinearity was not a concern, as tolerance values were 0.96 and higher while VIF < 1.35 (Lavery et al, 2019). The analysis revealed that higher OCB scores, as reported by the supervisors, predicted higher levels of WFF (β = 0.20, p < 0.05), thus supporting H1.…”

OCB-Work-Family Facilitation: Is It Positive for All Attachment Orientations?

The present study seeks to expand on research concerning the benefits of organizational citizenship behaviors (OCBs) to work-family facilitation (WFF) by integrating the theoretical framework of the attachment personality perspective (Bowlby, 1982). We hypothesized that OCB would enhance WFF for employees having lower levels of avoidance and anxious orientations but reduce WFF for employees with higher levels of avoidance and anxiety orientations. Two studies were conducted to test these hypotheses. Study 1 adopted a cross-sectional design, and Study 2 implemented a diary procedure. In Study 1, employees from a pharmaceutical company completed attachment orientations and WFF questionnaires, whereas their direct supervisors assessed the participants' OCB. In Study 2, attachment orientations of 108 participants were assessed, with OCB and WFF measures collected over 10 days. Findings from both studies supported our hypotheses relating to avoidance orientations. Performing OCB can enhance WFF, with the effect stronger for employees having lower avoidance orientations. However, findings regarding anxiety orientations were non-significant. A better understanding of the role that attachment orientations play in the OCB -WFF association may facilitate implementing possible interventions that could benefit both the organization and the family.

“…The degree of multicollinearity was assessed with the tolerance value and the variance inflation factor (VIF). When the tolerance value was >0.10 and the VIF was <10 for the predictor variables, there were no serious problems with multicollinearity ( López, 1998 ; Dormann et al, 2013 ; Lavery et al, 2017 ). A p -value of 0.005 represented significant differences.…”

Study of Sexual Satisfaction in Different Typologies of Adherence to the Sexual Double Standard

2021

The sexual double standard (SDS) refers to the acceptance of different criteria to assess the same sexual behavior in men and women. To date, the few studies that have addressed the relationship between SDS and sexual satisfaction have obtained inconclusive results. In addition, no study has analyzed sexual satisfaction in people who maintain different forms of adherence to the SDS. This study establishes three SDS typologies of adherence (man-favorable, woman-favorable, egalitarian) in two areas of sexual behavior (sexual freedom and sexual shyness) to examine the predictive capacity of personal variables (age, social dominance orientation, propensity for sexual excitation/inhibition), interpersonal variables (relationship satisfaction) and social variables (gender norms about sexual behaviors) in sexual satisfaction. A sample of 1194 heterosexual adults (51.1% men, 48.8% women) aged between 18 and 87 years (M = 40.63; SD = 15.67), who had been in a relationship for more than 6 months, was evaluated. In men, the highest sexual satisfaction levels were obtained in the egalitarian typology in the sexual freedom area. In women, no significant differences were found between the typologies of adherence to the SDS. Regression models showed that relationship satisfaction was the main predictor of sexual satisfaction in all the typologies in both men and women. In addition, the predictive relationship of personal variables with sexual satisfaction varied according to gender and the SDS adherence type. The results show the importance of studying sexual satisfaction by taking into account not only the differences between men and women. Furthermore, it is essential to consider other differences between people; for example, the difference that derives from the way of psychologically internalizing attitude toward the SDS.

“…Robust standard errors were used for the Poisson GEE given the clustering for the incidence of diarrhea, ARI and malnutrition within districts [ 62 , 63 ]. Multicollinearity was assessed using correlation coefficients and the Variance Inflation Factor (VIF) with cut-off values of ≥0.8 and ≥ 10, respectively [ 64 ].…”

Background Approximately one-third of pregnant and postnatal women in Ethiopia experience depression posing a substantial health burden for these women and their families. Although associations between postnatal depression and worse infant health have been observed, there have been no studies to date assessing the causal effects of perinatal depression on infant health in Ethiopia. We applied longitudinal data and recently developed causal inference methods that reduce the risk of bias to estimate associations between perinatal depression and infant diarrhea, Acute Respiratory Infection (ARI), and malnutrition in Gondar Town, Ethiopia. Methods A cohort of 866 mother-infant dyads were followed from infant birth for 6 months and the cumulative incidence of ARI, diarrhea, and malnutrition were assessed. The Edinburgh Postnatal Depression Scale (EPDS) was used to assess the presence of maternal depression, the Integrated Management of Newborn and Childhood Illnesses (IMNCI) guidelines were used to identify infant ARI and diarrhea, and the mid upper arm circumference (MUAC) was used to identify infant malnutrition. The risk difference (RD) due to maternal depression for each outcome was estimated using targeted maximum likelihood estimation (TMLE), a doubly robust causal inference method used to reduce bias in observational studies. Results The cumulative incidence of diarrhea, ARI and malnutrition during 6-month follow-up was 17.0% (95%CI: 14.5, 19.6), 21.6% (95%CI: 18.89, 24.49), and 14.4% (95%CI: 12.2, 16.9), respectively. There was no association between antenatal depression and ARI (RD = − 1.3%; 95%CI: − 21.0, 18.5), diarrhea (RD = 0.8%; 95%CI: − 9.2, 10.9), or malnutrition (RD = -7.3%; 95%CI: − 22.0, 21.8). Similarly, postnatal depression was not associated with diarrhea (RD = -2.4%; 95%CI: − 9.6, 4.9), ARI (RD = − 3.2%; 95%CI: − 12.4, 5.9), or malnutrition (RD = 0.9%; 95%CI: − 7.6, 9.5). Conclusion There was no evidence for an association between perinatal depression and the risk of infant diarrhea, ARI, and malnutrition amongst women in Gondar Town. Previous reports suggesting increased risks resulting from maternal depression may be due to unobserved confounding.
